External Components/Crystal Selection
A minimum number of external components are required for proper oscillation. For a crystal input, one
22pF load capacitor should be connected to each of the X1 and X2 pins and ground, and a parallel
resonant 14.318 MHz, 16pF load, crystal is recommended. Values near these are acceptable, as is a series
resonant crystal, but either will result in frequencies which are slightly (up to 0.06%) different from the
ideal. For a clock input, connect to X1 and leave X2 unconnected. A decoupling capacitor of 0.1F should
be connected between VDD and GND, and 33
terminating resistors may be used on the clock outputs.
These terminating resistors are unnecessary for clock traces less than 1” (25mm).
